I think this issue also occurs on Jessie (and testing/unstable) when
installing a gem native extension. To reproduce in a fresh chroot:
# apt-get -y install ruby
$ GEM_HOME=~/.gem gem install rainbow
This produces the following output on my system:
-8<-------------------------------------------------------------------
Building native extensions. This could take a while...
ERROR: Error installing rainbow:

Similar errors have been reported in some AskUbuntu questions:
https://askubuntu.com/q/872399https://askubuntu.com/q/567423
The reason I think the issue is related to this bug is that the
problematic command line is built from Gem.bin_path at
lib/rubygems/ext/rake_builder.rb:23:
"#{Gem.ruby} -rubygems #{Gem.bin_path('rake', 'rake')}"
Is there a workaround for installing gem native packages other than
`sudo gem install`?
